I was trying to restore a checkpoint using the restore functionality and I have the code below
def restore_agent( self, checkpoint_path:str='', restore_search: bool = False, resume_unfinished: bool = True, resume_errored: bool = False, restart_errored: bool = False, ): # if restore_search: # self.search_alg = self.search_alg.restore_from_dir(self.local_dir) if checkpoint_path == '': checkpoint_path = self.results.get_best_result().checkpoint._local_path restored_agent = tune.Tuner.restore( checkpoint_path, restart_errored=restart_errored, resume_unfinished=resume_unfinished, resume_errored=resume_errored, ) self.results = restored_agent.fit() self.search_alg.save_to_dir(self.local_dir) return self.results
Then I did
res = drl_agent.restore_agent(checkpoint_path=best_result.checkpoint._local_path)
But I am getting an error that the correct path was not passed. What is the issue here? The docs are not clear on what to pass to the checkpoint path.
Also, the restore scheduler and search space are a bit confusing in what it tries to do and what are the best practices are if we run multiple tune runs.
